Title

DEMOGRAPHY OF BEMISIA TABACI (HEM.: ALEYRODIDAE) ON SENSITIVE AND RESISTANT TOMATO CULTIVARS TREATED WITH EXTRACTION OF FUMITORY, FUMARIA PARVIFLORA (LAMARK)

Abstract

 Cotton whitefly, Bemisia tabaci (Gennadius) is one of the most important pests of agronomic in greenhouse’s crops and ornamental plants. In this study, the effect of sublethal dose of Fumria parviflora (Lamark) (Papaverales: Fumariaceae) extract on the age-stage, two-sex life table parameters of B. tabaci was evaluated. While insect was reared on sensitive (Ergon) and resistant (Cal j n3) tomato cultivars. A total of 30 adult insects of the same age were released into glass cage and the adults were removed after 24 hours. All less than 24 hours old eggs remained and the fecundity were recorded daily until the end of the last day of life. Experiments were done in greenhouse under controlled condition; 27 ± 2°C , 50 ± 5 %rh and 16 h light/8 h dark. Results showed lower INTRINSIC RATE OF INCREASE, gross reproductive rate and net reproductive rate of pest on resistant varieties Cal j n3 with amount of 0.062 d-1, 37.2 egg/individual and 10.1 egg/individual respectively, than insects reared on susceptible cultivar, Eregon which were treated with Fumaria extract with amount of 0.071 d-1, 39.85 egg/individual and 13.82 egg/individual respectively. The INTRINSIC RATE OF INCREASE reduction in control treatment of Cal j n3 cultivar showed the effect of resistant cultivars on pest population dynamic. Although extract of fumaria application increased a crash of population on both cultivars, coeffect of resistancy and herbal pesticide application showed a better result. The highest INTRINSIC RATE OF INCREASE was observed in control and ergon  treatments with 0.1 d-1 and the lowest rate was recorded on F. parviflora+ Cal j n3 (0.06 d-1) ones. Therefore, usage of resistant varieties beside the herbal pesticides application showe deeply effect on this pest population density and is very important in its IPM strategy.
